429dd9aff1 Advertise QoS Map support based on driver capability
Do not assume the driver supports QoS Mapping, but instead, advertise
support for this only if CONFIG_INTERWORKING is defined and driver
indicates support for configuring QoS Map.

dcca2219ae wpa_supplicant: Update channel switch driver interface
Add csa_settings struct which holds parameters for CSA. Change driver
interface for switch_channel(), so that it will receive this struct and
not only the new frequency as it was before. This allows wpa_supplicant
to provide all the required parameters (beacons, proberesp, assocresp,
CSA IE) which are required by cfg80211 implementation.

795baf773f hostapd: Filter channel list updated events after country code change
We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

f0793bf191 hostapd: Wait for channel list update after country code change
If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.

calculate the time when the driver last updated the BSS entry. In

3d9975d5b0 Do not trigger fast reconnection on locally generated deauth/disassoc
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.

Fix this by adding a new deauth/disassoc event variable to indicate

4dc03726de Delay STA entry removal until Deauth/Disassoc TX status in AP mode
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.

This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.

With the new kernel functionality coming to Linux to allow off-channel
TX, we can take advantage of that in the P2P code that currently uses
remain-on-channel. If a driver advertises support for it, it will be
asked to handle off-channel TX by itself.

0d7e5a3a29 Allow AP mode to disconnect STAs based on low ACK condition
The nl80211 driver can report low ACK condition (in fact it reports
complete loss right now only). Use that, along with a config option, to
disconnect stations when the data connection is not working properly,
e.g., due to the STA having went outside the range of the AP. This is
disabled by default and can be enabled with disassoc_low_ack=1 in
hostapd or wpa_supplicant configuration file.

If a station received unprotected Deauthentication or Disassociation
frame with reason code 6 or 7 from the current AP, there may be a
mismatch in association state between the AP and STA. Verify whether
this is the case by using SA Query procedure. If not response is
received from the AP, deauthenticate.

directly from the driver wrappers.

9008a3e44d Merge get_seqnum_igtk() driver op with get_seqnum()
IEEE 802.11w uses distinct key indexes (4 and 5) so the same
get_seqnum() handler can be used to fetch packet number for both
TKIP/CCMP and BIP(using IGTK).

Since the new get_seqnum_igtk() handler was not actually implemented by
any driver wrapper, this may also fix BIP/IGTK sequence number reporting
with driver_nl80211.c.

There was code for configuring this, but no driver wrapper actually

differently.

if_add/if_remove can now be used as the generic driver ops for adding

driver_nl80211.c is now including this code unconditionally, so that
the functions are not limited only for hostapd.

e6b8efeba0 nl80211: Add debug prints for BSS status in scan results
Print what the kernel believes the current BSS status (authenticated
or associated) is in scan results. In addition, check whether this
matches with the state that wpa_supplicant believes the driver to be
in.

This does not change the actual behavior, but will provide information
that will help in debugging potential issues where cfg80211/mac80211
seems to get into a different state from wpa_supplicant. In addition,
this provides an easy location for a workaround that could be added to
clear cfg80211/mac80211 state for unknown BSSes.

This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.

In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.

0194fedb46 driver_nl80211: Fix MLME key settings for static WEP
Current wpa_supplicant has a bug with WEP keys, it adds a zero-length
sequence counter field to netlink which the kernel doesn't accept.

Additionally, the kernel API slightly changed to accept keys only when
connected, so we need to send it the keys after that. For that to work
with shared key authentication, we also include the default WEP TX key
in the authentication command.

To upload the keys properly _after_ associating, add a new flag
WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE indicating that the driver
needs the keys at that point and not earlier.
